Why does Update() calls itself again and again?

I’m new in Unity gaming and making android game. I am implementing the menu screens before the game starts. I have a 15 objects on the screen that can be clicked to select the players i want in my game.

to touch the object i have separate script for each object, and I add that player name in my List when clicked. The problem is that if I click my object once, and then check the size of my List, it gives either 5 or 4 or even more than that. Is it because my Update() method is being called more than once? Please tell me what to do?

My script is as follows:

using UnityEngine;
using System.Collections;

public class midge : MonoBehaviour {

	// Use this for initialization
	void Start () {
	
	}
	
	
	void Update () {
		
		if (Input.touchCount == 1)
		{
			Vector3 wp = Camera.main.ScreenToWorldPoint(Input.GetTouch(0).position);
			Vector2 touchPos = new Vector2(wp.x, wp.y);
			if (collider2D == Physics2D.OverlapPoint(touchPos))
			{
				
				Material newMat = Resources.Load("New Material", typeof(Material)) as Material;
				gameObject.renderer.material = newMat;
				PlayersManager.objPlayerList.Add(PlayersManager.setPlayerObject("Midge"));
				countausplayer.countteam++;
				
				
			}
			
		}
	}

	}

Please guide me where am I going wrong?? It’s really urgent!!

Update is called each frame.

So now your function will check if there is a touch for each frame and add your player to the list for the time your finger is on the screen.

You need:

if (Input.touchCount == 1 && touchPhase.Begin)
{
    // Perform your action here
}
